SHIELD FOR RAILWAY-CARS.

SPECIFICATION forming part` of Letters Patent No. 257,231, dated May 2, 1882.

Application led August 8, 1881. (No model.)

vTo all whom it may concern Be it known that we, SE'rH G. Mason and JOHN L. HANsoN, citizens ot the United States, and both residents of Somerville, in the county of Middlesex and State of Massachusetts, have invented an Improvement upon our patent issued November 16, 1880, No. 234,416, entitled Shields for Railway-Gars; and we do hereby declare that the following is a full and exact description thereof. The objects of our invention are, first, to improve the construction of the shields; second, the manner of attaching and operating them by more reliable and simple devices.

Our invention consists in the combination and arrangement of oneppermanent and one movable shield, cylinder-post, with operatingpiston, supporting-brace, spiral spring-bolt, curved shield, and shield-doors. A fuller description is exhibited by reference to the drawings, in which- Figure l is the side view of a car with the lifeprotectng shield. Fig. 2 represents the cylinder-post attached to the bottom of the car, and its operating-piston with bolt through the post. Fig. 3 shows a ange on the top ot' the post which is conlined to the bottom of the oar by bolts. Fig. -4 shows side elevation of the car-steps with shield-doors to iill the space between them closed by a swivel-bar when the cars are in motion.

A indicates the space between the bottom of the ear and the top of the permanent shield; B, the braces which support the cylinderposts, extending from the bottom of the car tothe bottom ot' the permanent shield, showing two or more braces to each post.

O is the post, as seen in Fig. 2, showing the mode ot' raising or lowering the movable shieldin case obstructions are met upon the track at the end ot' the shield, when the shield will rise till the obstruction is passed, then it falls to its proper place, which is about two inches above the rail and about two inches outside the car-wheels.

D shows the piston operating` inside the post to raise and lower the movable shield running up on the inside ofthe permanent shield.

E represents the straps which confine the permanent shield to the post.

F shows the bolt permanently fastened to the post, guiding the piston through a slot in its up-and-down motion, thus holding the piston and movable shield at the required distance ot about two inches above the rail,

there resting on the bolt at the upward part of the slot in the piston; G, the iiange at the top ot' the post by which the shields, post, and piston are confined to the bottom of the car by bolts.

H'is the permanent shield, as seen in Fig. l, and is fastened to the posts by straps and bolts, as seen in Fig. 2, and thus made stationary. l

H shows the movable shield with its upand-down movement, thus showing an improvement over the patent hereinbefore referred to in the support ot' the shield to the car. We also discontinue the use of the weights, pulleys, brackets, cords, and circular motion in raising or lowering the shields, saving the projection (before required) on the outside of the car, and substituting therefor a horizontal division of the shield, making one movable one rise and pass over obstacles that the lower end of each movable shield, so ar' `ranged that when it has been struck by an obstacle the bolt springs back, leaving a curve on the end of the shield, so that when the obstacle is met the shield will rise, and the bolt then springs back to its proper place, closing the aperture of the curve.

J shows the curve at the ends of movable shield,as seen in Fig. 2', when the bolt has met an obstacle.

What we claim as our invention, and desire to secure by Letters Patent, is-

l. The combination, with a railway-car, ot" the cylinder-posts, pistons, divided shields, and their attaching mechanism, all arranged and operating in the manner set forth.

2. The spiral spring-bolt and curve, with its connecting mechanism at the ends of the movable shield, all arranged substantially as and for the purposes specified.
